Application filed November 7, 1889. Serial No. 329,581. (No model.)

T0 64% whom it may concern:

Be it known that 1, JAMES C. ANDERSON, a citizen of the United States, residing at Highland Park, in the county of Lake and State of Illinois, have invented new and useful Improvements in Brick-Kilns; and I do hereby declare the following to be a full, clear, and exact description of said inventiomreference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates to improvements in kilns for burning brick and other clay articles with coal-oil or other hydrocarbons.

The object of my invention is to provide means for burning brick, 850., with coal-oil or other hydrocarbons in a continuous, eXpeditious, and economical manner.

My invention consists of a tunnel-kiln in which cars containing the articles to be burned are run, and in introducing the oil into a jacketed chamber in the arch of the tunnel, where it is ignited, the milder portions of the flame being passed into the interior of the tunnel and through the articles to be burned, as will more fully hereinafter appear.

Referring to the drawings, Figure l is a vertical sectional view of my improved. kiln, taken on the line as a; of Fig. 3. Fig. 2 is a longitudinal vertical sectional view. Fig. 3 is a longitudinal vertical sectional view of that portion of the kiln where the oil is injected into the jacketed space and burned.

Aindicates the kiln, consisting of an arched tunnel-way B, provided with tracks 0 for the reception of the cars D, said cars being provided with a fire-proof floor E to protect the running-gear of the car from becoming injured by the heat, and on which the brick or other articles to be burned. are piled in the usual way of hacking in kilns. The bottoms of the cars are somewhat wider than the pile of brick to be burned and are provided with troughs F, in which sand or water is placed. The insides of the tunnel are provided with downwardly-projecting ledges G and with heavy sheet-metal strips H, which project down into the troughs F, and thus form a seal to prevent the heat from passing down the sides of the tunnel to the trucks of the car, and

ing into the upper portions of the tunnel, which would in a great measure neutralize the effect of the products of combustion. The spaces between the cars are also provided with fire-resisting material, so as to prevent the heat from passing down to the trucks. A portion of the arch of the tunnel is doublewalled, as shown at I, so as to form a jacketed space K, into which the oil-supply pipes L project, said pipes being admitted at one end of the jacketed space K, as shown in Figs. 2 and 3. The other end of the jacketed space K is provided with a series of apertures a, which open into the tunnel and through which the flame passes into and through the articles to be burned, giving up its energy or strength to the articles on the train of cars, and finally passes out at the stack N.

In operation the oil is ignited when it e11- ters the jacketed space K and gives up the hottest and most destructive portion of its flame to the inner lining of the jacketed space, and through which it is communicated to the brick on the cars, the tail of the flame, or the least destructive portion of the products, which partakes of the nature of a hydrocarbon gas, being forced out'through the openings 0, and into and through the articles to be burned, as already indicated, and gives up its heat to the fresh brick coming in through the end of the tunnel at Q to water-smoke them and bring them gradually up to the proper heat for receiving the final firing without seriously warping or injuring them. The water smoke thus driven off may be collected from the top of the tunnel and brought for ward to the jacketed space K, into which it is projected and mingled with the hydrocarbon to facilitate combustion.

The length of the jacketed space K is somewhat longer than the length of one of the cars,

. and the cars are stopped a short distance in front of the openings a, so that the flame entering through said openings will be proj ected down between the cars and drawn forward by the draft of the stack through the brick 011 the cars in this portion of the kiln.

What I claim, and desire to secure by Letters Patent, is

also to prevent the inflow of air from ascend- 1. A kiln for burning brick, in which oil is used as a fuel, consisting of a tunnel having a jacketed space in the top thereof, into which the oil is introduced and burned, as set forth.

2. A kiln for burning brick of the character described, provided with a jacketed space in the roof thereof, into which the oil is introduced at one end and burned, the other end of said jacketed space being provided with apertures through which the milder portions of the-flame pass and are brought into contact with the articles to be burned, as set forth.

3. A kiln for burning brick of the character described, provided with a jacketed space in the roof thereof, into which the oil is introduced at one end and burned, the other end of said jacketed space being provided with apertures through which the milder portions of the flame pass and are brought into contact with the articles to be burned, and a stack located at the entrance end of the tunnel, whereby the products of combustion are all utilized to burn, heat, and water-smoke the articles on the cars in their passage into the tunnel.

In testimony whereof I affix my signature in the presence of two subscribing witnesses.
